[0032] The present invention will be further described below in conjunction with the accompanying drawings.
[0033] A method for preparing high-durability kiln furniture for positive electrode materials of lithium electric power batteries. The inner and outer layers of the kiln furniture are made of different materials; the base layer of the outer layer and the anti-corrosion layer of the inner layer are laminated and pressed, and then fired; Pressure treatment ensures strong bonding force, high yield and low cost; and the design of the inner and outer layers can not only use the outer layer to obtain good heat resistance, but also use the inner layer to obtain strong alkali resistance, reaching the weight of the kiln furniture. A balance of performance. The anti-corrosion layer is specifically arranged on the inner bottom of the base layer, with a thickness of 3-5mm; as attached figure 2 As shown, the hatched part represents the base layer part, and the black strip inside ...
